Using Plus Seven Control
The following procedure is performed on your RDM lighting control device.
Step 1: Select a starting color point for the fixture output using the standard control
channels for RGB, HSI, etc.
Step 2: Set the first additional channel to a value between 51 and 100% to activate Plus
Seven.
Step 3: Refine the fixture output by altering one or more of the 7 individual color
channels.
•
The starting point for each color is defined by the original color selection in
step 1.
• The brightness of each color can be increased or decreased from the starting
point to any value between zero and full output.
• Colors already at full output will not change when the Plus 7 channels are
moved up from the starting point, and colors already at zero output will not
change when the Plus 7 channels are moved down from the starting point.
LED Settings
Output
Output is the way and amount to which the fixture constrains the overall power going to the
LED array, which determines how consistent the fixture’s brightness may be. Use Output
to choose the optimal balance between two competing performance parameters, maximum
brightness and output consistency, by adjusting:
• How much the fixture limits the overall power to the LED array.
• How the fixture reduces output as internal fixture components heat up during use or in
high ambient temperatures.
The output options are as follows.
Regulated
Regulated is a moderately constrained power or brightness with consistent output under
typical use. Power to the LEDs is separately regulated in order to maintain consistent
brightness during the initial fixture warm-up period. This is recommended for most indoor
applications.
Protected
Protected provides the most consistent output possible with the greatest potential for
reduced overall brightness. This is best for outdoor use, changing environmental
temperatures, and applications with high requirements for consistency in extreme operating
conditions.
N o t e : Once any one of the seven individual color channels is altered from its neutral
starting position, the settings for the original color point may no longer reflect the
actual output of the fixture.
When using RGB, HSI, HSIC, or Studio profile for color selection, each fixture
makes accommodations for the specific LEDs in its array and produces output that
is consistent with other fixtures, whether or not they use LEDs from the same
production batch.
Operating with Plus Seven enabled can override this calibration, and multiple
fixtures may produce slightly different outputs when individual color channels are
altered from their neutral starting points..
